After hopping around a couple of karaoke bars at midnight on a Saturday, and finding out they were full and we'd have to wait 30+ minutes, we ended up coming here and got a room within 10 minutes. For a group of 6, it came out to $60 for 2 hours, so $10 each, which we paid at the beginning.
The room fit us all comfortably. There is a HUGE selection of Korean songs (even a lot of recent ones), but not so much for English. They have a lot of notable English pop songs, both old and new (ish... maybe from like 3 or 2 years ago) but if you're looking for anything really recent, you won't find it here.
Nevertheless, it was a very fun experience. Or maybe I'm just saying that because of the alcohol we consumed and the group of friends I was with.
It was quite expensive for alcohol: 2 smirnoff ice and a bottle of soju for $32, but once you start taking a couple shots, the price doesn't seem to matter anymore...
If I'm ever in the area and other karaoke bars are closed, I would come here again, but as a first choice, maybe not. I'd probably go and explore other karaoke bars until I find one that I'm completely satisfied with. But I guess, like they say, "it's not where you are, it's who you're with."
